How long has internet been going for?

Answer 1

Little history of the internet to start with :

The USSR's launch of Sputnik spurred the United States to create the Advanced Research Projects Agency (ARPA, later known as the Defense Advanced Research Projects Agency) in February 1958 to regain a technological lead. ARPA created the Information Processing Technology Office (IPTO) to further the research of the Semi Automatic Ground Environment program, which had networked country-wide radar systems together for the first time. J. C. R. Licklider was selected to head the IPTO, and saw universal networking as a potential unifying human revolution. Licklider recruited Lawrence Roberts to head a project to implement a network, and Roberts based the technology on the work of Paul Baran who had written an exhaustive study for the U.S. Air Force that recommended packet switching (as opposed to Circuit switching) to make a network highly robust and survivable. After much work, the first node went live at UCLA on October 29, 1969 on what would be called the ARPANET, the "eve" network of today's Internet.

The first TCP/IP wide area network was operational by 1 January 1983 , when the United States' National Science Foundation (NSF) constructed a university network backbone that would later become the NSFNet. (This date is held by some to be technically that of the birth of the Internet.) It was then followed by the opening of the network to commercial interests in 1985. Important separate networks that offered gateways into, then later merged into the NSFNet include Usenet, Bitnet and the various commercial and educational X.25 Compuserve and JANET. Telenet (later called Sprintnet), was a large privately-funded national computer network with free dialup access in cities throughout the U.S. that had been in operation since the 1970s. This network eventually merged with the others in the 1990s as the TCP/IP protocol became increasingly popular. The ability of TCP/IP to work over these pre-existing communication networks allowed for a great ease of growth. Use of Internet as a phrase to describe a single global TCP/IP network originated around this time.

The network gained a public face in the 1990s. In August 1991 CERN, which straddles the border between France and Switzerland publicized the new World Wide Web project, two years after Tim Berners-Lee had begun creating HTML, HTTP and the first few web pages at CERN.

An early popular web browser was ViolaWWW based upon HyperCard. It was eventually replaced in popularity by the Mosaic web browser. In 1993 the National Center for Supercomputing Applications at the University of Illinois at Urbana-Champaign released version 1.0 of Mosaic and by late 1994 there was growing public interest in the previously academic/technical Internet. By 1996 the word "Internet" was common public currency, but it referred almost entirely to the World Wide Web.

Meanwhile, over the course of the decade, the Internet successfully accommodated the majority of previously existing public computer networks (although some networks such as FidoNet have remained separate). This growth is often attributed to the lack of central administration, which allows organic growth of the network, as well as the non-proprietary open nature of the Internet protocols, which encourages vendor interoperability and prevents any one company from exerting too much control over the network


From this about i would say internet as we know it today has been existence for roughly 10 yrs now.

Answer 2

The internet has existed in one form or another since the 1960's. It was originally a network of only a few computers in the government and at Universities. The current incarnation of the internet, or the "World Wide Web" can into being in the early 1990's after the invention of HTML and the graphical web browser MOSAIC.

Answer 6

1957

The USSR launches Sputnik, the first artificial earth satellite. In response,the United States forms the Advanced Research Projects Agency (ARPA) within theDepartment of Defense (DoD) to establish US lead in science and technology applicable to the military.

1962

RAND Paul Baran, of the RAND Corporation (a government agency), was commissioned by the U.S. Air Force to do a study on how it could maintain its command and control over its missiles and bombers, after a nuclear attack. This was to be a military research network that could survive a nuclear strike, decentralized so that if any locations (cities) in the U.S. were attacked, the military could still have control of nuclear arms for a counter-attack.

Baran's finished document described several ways to accomplish this. His final proposal was a packet switched network.

"Packet switching is the breaking down of data into datagrams or packets that are labeled to indicate the origin and the destination of the information and the forwarding of these packets from one computer to another computer until the information arrives at its final destination computer. This was crucial to the realization of a computer network. If packets are lost at any given point, the message can be resent by the originator."

1968

ARPA awarded the ARPANET contract to BBN. BBN had selected a Honeywell minicomputer as the base on which they would build the switch. The physical network was constructed in 1969, linking four nodes: University of California at Los Angeles, SRI (in Stanford), University of California at Santa Barbara, and University of Utah. The network was wired together via 50 Kbps circuits.

1972

The first e-mail program was created by Ray Tomlinson of BBN.

The Advanced Research Projects Agency (ARPA) was renamed The Defense Advanced Research Projects Agency (or DARPA)

ARPANET was currently using the Network Control Protocol or NCP to transfer data. This allowed communications between hosts running on the same network.

1973

Development began on the protocol later to be called TCP/IP, it was developed by a group headed by Vinton Cerf from Stanford and Bob Kahn from DARPA. This new protocol was to allow diverse computer networks to interconnect and communicate with each other.

1974

First Use of term Internet by Vint Cerf and Bob Kahn in paper on Transmission Control Protocol.

1976

Dr. Robert M. Metcalfe develops Ethernet, which allowed coaxial cable to move data extremely fast. This was a crucial component to the development of LANs.

The packet satellite project went into practical use. SATNET, Atlantic packet Satellite network, was born. This network linked the United States with Europe.Surprisingly, it used INTELSAT satellites that were owned by a consortium of countries and not exclusively the United States government.

UUCP (Unix-to-Unix CoPy) developed at AT&T Bell Labs and distributed with UNIX one year later.

The Department of Defense began to experiment with the TCP/IP protocol and soon decided to require it for use on ARPANET.

1979

USENET (the decentralized news group network) was created by Steve Bellovin, a graduate student at University of North Carolina, and programmers Tom Truscott and Jim Ellis. It was based on UUCP.

The Creation of BITNET, by IBM, "Because its Time Network", introduced the "store and forward" network. It was used for email and listservs.

1981

National Science Foundation created backbone called CSNET 56 Kbps network for institutions without access to ARPANET. Vinton Cerf proposed a plan for an inter-network connection between CSNET and the ARPANET.

1983

Internet Activities Board (IAB) was created in 1983.

On January 1st, every machine connected to ARPANET had to use TCP/IP. TCP/IP became the core Internet protocol and replaced NCP entirely.

The University of Wisconsin created Domain Name System (DNS). This allowed packets to be directed to a domain name, which would be translated by the server database into the corresponding IP number. This made it much easier for people to access other servers, because they no longer had to remember numbers.

1984

The ARPANET was divided into two networks: MILNET and ARPANET. MILNET was to serve the needs of the military and ARPANET to support the advanced research component, Department of Defense continued to support both networks.

Upgrade to CSNET was contracted to MCI. New circuits would be T1 lines,1.5 Mbps which is twenty-five times faster than the old 56 Kbps lines. IBM would provide advanced routers and Merit would manage the network. New network was to be called NSFNET (National Science Foundation Network), and old lines were to remain called CSNET.

1985

The National Science Foundation began deploying its new T1 lines, which would be finished by 1988.

1986

The Internet Engineering Task Force or IETF was created to serve as a forum for technical coordination by contractors for DARPA working on ARPANET, US Defense Data Network (DDN), and the Internet core gateway system.
Backbones: 50Kbps ARPANET, 56Kbps CSNET, 1.544Mbps (T1) NSFNET, plus satellite and radio connections - Hosts: 2308

1987

BITNET and CSNET merged to form the Corporation for Research and Educational Networking (CREN), another work of the National Science Foundation.
Backbones: 50Kbps ARPANET, 56Kbps CSNET, 1.544Mbps (T1) NSFNET, plus satellite and radio connections - Hosts: 28,174

1988

Soon after the completion of the T1 NSFNET backbone, traffic increased so quickly that plans immediately began on upgrading the network again.
Backbones: 50Kbps ARPANET, 56Kbps CSNET, 1.544Mbps (T1) NSFNET, plus satellite and radio connections - Hosts: 56,000

1990

(Updated 8/2001) Merit, IBM and MCI formed a not for profit corporation called ANS, Advanced Network & Services, which was to conduct research into high speed networking. It soon came up with the concept of the T3, a 45 Mbps line. NSF quickly adopted the new network and by the end of 1991 all of its sites were connected by this new backbone.

While the T3 lines were being constructed, the Department of Defense disbanded the ARPANET and it was replaced by the NSFNET backbone. The original 50Kbs lines of ARPANET were taken out of service.

Tim Berners-Lee and CERN in Geneva implements a hypertext system to provide efficient information access to the members of the international high-energy physics community.

1991

CSNET (which consisted of 56Kbps lines) was discontinued having fulfilled its important early role in the provision of academic networking service. A key feature of CREN is that its operational costs are fully met through dues paid by its member organizations.

The NSF established a new network, named NREN, the National Research and Education Network. The purpose of this network is to conduct high speed networking research. It was not to be used as a commercial network, nor was it to be used tosend a lot of the data that the Internet now transfers.
Backbones: Partial 45Mbps (T3) NSFNET, a few private backbones, plus satellite and radio connections - Hosts: 617,000
1992
Internet Society is chartered.

World-Wide Web released by CERN.

NSFNET backbone upgraded to T3 (44.736Mbps)
Backbones: 45Mbps (T3) NSFNET, private interconnected backbones consisting mainly of 56Kbps, 1.544Mbps, plus satellite and radio connections - Hosts: 1,136,000
1993
InterNIC created by NSF to provide specific Internet services: directory and database services (by AT&T), registration services (by Network Solutions Inc.), and information services (by General Atomics/CERFnet).

Marc Andreessen and NCSA and the University of Illinois develops a graphical user interface to the WWW, called "Mosaic for X".
Backbones: 45Mbps (T3) NSFNET, private interconnected backbones consisting mainly of 56Kbps, 1.544Mbps, and 45Mpbs lines, plus satellite and radio connections - Hosts: 2,056,000
1994
No major changes were made to the physical network. The most significant thing that happened was the growth. Many new networks were added to the NSF backbone.Hundreds of thousands of new hosts were added to the INTERNET during this time period.

Pizza Hut offers pizza ordering on its Web page.

First Virtual, the first cyberbank, opens.

ATM (Asynchronous Transmission Mode, 145Mbps) backbone is installed on NSFNET.
Backbones: 145Mbps (ATM) NSFNET, private interconnected backbones consisting mainly of 56Kbps, 1.544Mbps, and 45Mpbs lines, plus satellite and radio connections - Hosts: 3,864,000
1995
The National Science Foundation announced that as of April 30, 1995 it would no longer allow direct access to the NSF backbone. The National Science Foundationcontracted with four companies that would be providers of access to the NSF backbone (Merit). These companies would then sell connections to groups, organizations, and companies.

$50 annual fee is imposed on domains, excluding .edu and .gov domains which are still funded by the National Science Foundation.
Backbones: 145Mbps (ATM) NSFNET (now private), private interconnected backbones consisting mainly of 56Kbps, 1.544Mbps, 45Mpbs, 155Mpbs lines in construction, plus satellite and radio connections - Hosts: 6,642,000
